Application filed January `20, 1921. Serial-Nofl.

. The invention relates to the constructionbe vsuch that'their upper surfaces do not of oil stills, the object being to increase the life thereof and improve thenoperation and tlie quality of the products.

In the accompanying drawings-q I Fig. l is a side elevation of an oil still embodying'my present invention, a portion being broken away to show the interior in longitudinal section. Fig. 2 is an enlarged section on the line 2, 2 of Fig. l.v Fig. 3 is an enlarged section of the left hand end of the still, as shown in Fig. 1, and on the line 3, 3 of Fig. 2, showing in elevation the inserted beams E. Fig. 4; is a horizontal section on the line 4, 4 of Fig. 1.

Similar letters of reference indicate parts. a.

A is an elongated cylindrical oil still of known type. On the sides of `the 4still are lugs H which rest upon verticalfstandards I which are preferably beams of H-shaped cross section, .the lower parts of which are I like imbeddedin the end piers B and the inter` mediate piers C said piers being of masonry. From said intermediate piers-the still is separated by narrow spaces D. When heated.

and so expanded, the still closes said spaces I) andbears upon the intermediate piers C. The oil to be distilled is placed in the still,

and deposits its coke residuum uponl thebottom of the still, as show-n at (r. The depth of the deposit wil-l depend" upon the grade of oil distilled. Where, for example,

the still is, say, forty Vfeet in length and e fourteen feet 1n diameter, with a certain grade of oil the depth of the coke deposit may be, say, twenty-six inches.

In practically using oil stills such, for eX'- ample, as shown at A, I have found that thel bottom sheets of the still are liable to sag between their supports and also to become rapidly deteriorated by the high heat to which they are subjected; and that the heat is not uniformly distributed. through the coke deposit but is greatest at the bottom and progressively less to the upper surface of said de osit. j

I have e iminated' both of these difficulties as follows: Within the still and on the bottom thereof, I rivet a number. of parallel longitudinal yiron beams E, preferably spaced at equal distances a art and intro` duced into the'still through t e man-holes F. The depth of these beams should preferably rality of longitu come above the upper surface of the coke deposit and lie some inches below said deposit surface.; .'Ihus in the preceding example, where the coke deposit is assumed to be twenty-six 'inches deep, the beams may be about twenty inches deep. A11 desired number of these beams may be use In the drawings I show three, each beam being prferably made 4in sections placed end to CII each beam are preferably staggered with respect to the joints between the sections of an adjacent beam', andit is further preferable that the joints should come directly abovethe several intermediate supports.

4These beams hold -up the bottom sheets of the still between the supports and efectually prevent their sagging when highlyheat'ed. Being securely joined in close metallic contactwth the floor of the still they also conduct heat from the bottom to the upper part of the coke deposit and thus deliver said heat to the places in said deposit when nor-` mally the heat `is lowest, thereby insuring a more uniform heat distribution throughout -said deposit. I have Yfound by actual experiment that the presence of the beams shortens the coking time by twenty per cent, and that therel is also produced greater economy of fuel and increased life of said bottom sheets because the heat is conducted away therefrom.

I claim: 1.l An oil cokingstill of the type set' forth, having its floor portion reinforced by a pluinal beam members secured to and in close metallic .contact with the in,- terior 'surface of said fioor portion and rojecting upwardly therefrom to distri 'ut'e heat-to the still contents. f

having its floor portion disposed over and adapted to be supported by one or more foundation piers, and a longitudinal interior beam member spanning rsaid piers and secured to andin `close metallic contact with the interior of said floor', whereby said floor portion is stiifened and the heatis distributed to the interior of the coke.

'In testimony lwhereof I havejaixed my signature.
